BACKGROUND OF THE INVENTION

1. Field

The present invention relates to a method, system, and article of manufacture for generating templates of nodes to structure content objects and steps to process the content objects.

2. Description of the Related Art

Independent units of information are unstructured in nature. Relationships and structure are introduced when the information units are presented in a logical order. Certain software programming techniques may be used to provide structure to unstructured information and processes, such as a workflow program that is used to generate a workflow process indicating specific operations performed at different nodes in a workflow, a database, and the use of hyperlinks in hypertext documents to link together documents in a logical ordering, etc. Once the structure is defined for the information and pages, it may be difficult to update or modify the structure and design, such as the case with linked hypertext documents providing linked pages of a user interface.

There is a need in the art for improved techniques to allow a developer to define structure for content objects and documents and processes used to process the documents and content objects, and use the documents and content objects for other technical or business processes.

SUMMARY

Provided are a method, system, and article of manufacture for generating templates of nodes to structure content objects and steps to process the content objects. A template is generated having a plurality of first level nodes representing a flow of tasks. A set of second level nodes representing a flow of steps is generated for at least one of the first level nodes to collectively perform the task represented by the first level node. A content object including information for a step represented by the node is associated with at least one node in the second level. Links are generated among the first level nodes and in each set of second level nodes indicating a logical ordering of the nodes and a direction of the flow of the tasks represented by the first level nodes and the flow of steps represented by the second level nodes. An end-user graphical user interface is generated from the generated nodes and links to direct an end user through the flow of tasks and steps represented by the nodes.

DETAILED DESCRIPTION

FIG. 1 illustrates a computing environment in which embodiments may be implemented. A system 2 includes a processor 4 and operating system 6. The operating system 6 implements a runtime environment in which programs, such as an authoring system 8, run. The authoring system 8 generates an authoring system graphical user interface (GUI) 10 to enable a developer to generate a structured flow or organization of content and steps for an end user to perform with respect to the content objects. Authoring GUI 10 generates a task model 12 comprising a first level template 14 having multiple nodes representing tasks to perform as part of the task model. One or more of the nodes representing the tasks may have an associated second level template 16. Each second level template 16 has multiple nodes representing a flow of steps to perform to implement the task associated with the second level template 16. The developer, using the authoring GUI 10, may associate a content object with one or more of the nodes of the second level templates 16. A content object may comprise a text document, file, executable program, etc. The content object may comprise a hypertext document including hypertext links to programs or pages of additional information, such as a help or Frequently Asked Questions (FAQ) page.

In one embodiment, each second level node may include a content object providing a control button to enable the user to proceed to a next step in the flow of steps. The templates 14 and 16 and content objects associated with the second level nodes may be stored in a content database 18. Although two levels of templates are described, there may be any number of levels of templates linking to each other where each second and further level of templates may provide content objects, steps and links to further levels of templates to perform certain steps and provide additional content objects in the flow of operations.

The developer may generate pages from the templates 14 and 16 for the task model 12 to form an end user graphical user interface (GUI) 20, where the templates and nodes are converted to pages through which the end user may progress according to the flow of operations of the nodes in the first and second level templates. The end user GUI 20 may be stored in a program that may be deployed to end users to perform the steps and review the content generated into the end user GUI 20. Further, the generated task model 12 may be stored and archived for further editing or later use. Yet further, the task model 12, comprising the first 14 and second 16 level templates, may be supplied to another application to consume. Such other applications receiving the task model 12 may run the flow of operations and consume the content objects represented in the templates 14 and 16.

FIG. 2 illustrates an instance of the authoring GUI 50 rendering a first level node template 52 having graphical shapes, e.g., boxes, representing task nodes, including Task 1, Task 2 . . . Task 5. The lines between the task nodes represent the flow of the tasks 1, 2 . . . 5 that collectively comprise a task model representing an overall task to accomplish, such as diagnose a technical problem with a device or program, perform a set of organizational operations to complete an overall business or technical task, process content objects, provide a guided tutorial through steps rendering the content objects, etc. The flows may provide an explanation without branching through the use of questions and answers or a flow that branches to other flows and levels of templates and content objects based on user answers to questions. An editor pane 54 includes task buttons, such as “New Task” that enables the developer to add a task box to the template 52, a “New Link” button to add a line connecting two tasks indicating a flow of operations from one task to another, and a “Save and Close” button to save the task model. The editor pane 54 further includes reusable tasks (“RT”), e.g., RT1, RT2 . . . RTn, that may be added to the first level node template 52. A reusable task comprises a task node that may be added to the first level template 52. Adding a reusable task node also adds the second level template associated with the reusable task node to the task model being generated.

FIG. 3 illustrates an instance of the authoring GUI 70 rendering a second level node template 72 having the steps representing operations to perform for an associated task, e.g., Task 2 in the example of FIG. 3, in the first level node template 52. The editor pane 74 includes a “New Step” button that enables the user to add graphical shapes, e.g., boxes, representing steps to perform and a “New Link” button that that allows the user to draw lines to define a logical ordering of the step nodes. The “Edit Pages” button allows the user to edit a content page associated with each step node. In the content page for the step nodes, the user may include information on operations for the user to perform for that step and include links or information on programs to run to perform the operations for that step. The end result steps or end steps may correspond to tasks in the first level template 52, such as tasks 3 and 5. This provides a flow of operations from a final step in a second level template 74 for a first level node, such as Task 2 in the first level template 52, to a subsequent first level node or Task, e.g., Tasks 3 or 5, according to the flow in the first level template 52.

The developer may further use the authoring GUI 10 to add metadata for the links and nodes, such as a label for the link or node, a description of the link or node, and design notes. This metadata assists the developer in editing the flows defined in the templates and documenting the templates.

With the described embodiments, the user may associate any type of content object with a step in the second level template 72, such as a text document, executable program, etc.

FIG. 4 illustrates an embodiment of an authoring GUI 90 implementation rendering a first level template 92 including task nodes providing a structure flow of tasks to diagnose a device or program. The tasks and flow comprise an introduction task 94, an identify symptoms task 96 to determine the symptoms or observable problems with the device being diagnosed, a collect data task 98 to collect data on device operations, an analyze data task 100 to analyze the collected data, an identify root cause task 102 to determine the problem with the device, and a validation solution task 104 to determine whether the solution is tenable. Moreover, many of the tasks may segue to a contact technical support task 106. The node for the contact technical support task 106 may comprise a content page having contact information for technical support. Further, many steps, such as steps 96, 100, 102, 104, may proceed to a problem fixed task 108 indicating an end to the flow.

FIG. 5 illustrates an embodiment of an instance of the authoring GUI 110 including the second level template 112 of nodes representing steps to perform for the first level analyze data task 100 (FIG. 4). From an introduction step 114, the step flow may proceed to test one of two components in the device or program being diagnosed. Each component analyzer step 116, 118 allows the user to install a different component tester at an installation step 120, 122. For component 1, the user may proceed to the installation step 120. At the analyze component 1 step 124, the user may be presented an associated content page with a link to allow the user to launch the component 1 tester or provide written instructions on how the user may analyze component 1. For component 2, the step flow proceeds to installation step 122 and/or to a decide version step 126 at which the end user may decide to proceed to steps 128 or 130 to use one of the two different versions of component 2 tester to analyze the component 2. After analyzing the components, the user may proceed to an evaluation step 132 or 134 to evaluate the results. The step node 132, 134 includes content pages including information to assist the user in analyzing the problem and allowing the user to select a next step in the flow, such as contact support 136, end session 138, identify the root cause 140. The end steps 136, 138, and 140 correspond to first level tasks 106, 108, and 102, respectively, in FIG. 4, to cause the flow to proceed to the next first level task in the task flow from the end step 136, 138 or 140 in the second level step flow.

FIG. 6 illustrates an embodiment of a page 150 displayed in the end-user GUI 20 generated from the analyze component 1 step 124 in the developer generated second level template 110 and the content page associated with the step 124. The analyze component page 150 includes text content 152 instructing the user to select a link 154 to launch the component 1 tester program if previously installed. Selecting the back button 156 and next button 158 causes the end-user GUI 20 to proceed to the page for a previous and subsequent steps, respectively, in the flow. Selection of the end session button 160 branches to the end session task 108 (FIG. 4) in the first level flow. The text content 162 also provides an explanation of the analyze step and manual operations the end user may perform in lieu of using the component 1 tester program that can be installed at step 120.

FIG. 7 illustrates an embodiment of a page 170 displayed in the end-user GUI 20 generated from a page associated with the evaluate step 132 for component 1 in the second level flow of FIG. 5. The page enables the user to select a further step 172, 174, 176, 178 corresponding to steps 118, 102, 108, and 106, respectively, in the second level step flow of FIG. 5. Further, end steps 136, 138, and 140 in the second level flow correspond to task 106, 108, and 102, respectively, in the first level task flow indicating the flow between steps and tasks in the model. Selection of one of the options 172, 174, 176, and 178 along with selection of the Next button 180 causes the flow to proceed to the next step and/or task in the flow of tasks and steps. Selection of the Back button 182 causes the end-user GUI 20 to render the content object for the previous step, which comprises the analyze component 1 step 124. Selection of the stop session button 184 causes the end-user user interface to proceed to the content page associated with the end session step 138 in FIG. 5, which corresponds to the end session task 108 in the first level task flow of FIG. 4.

FIG. 8 illustrates an embodiment of operations performed by the authoring system 8, which provides an authoring system GUI 10 enabling the developer to create first and second level nodes and content objects for the second level nodes that associates content and operations for an end-user GUI 20. The authoring system GUI 10 is invoked (at block 200) and enables the developer to perform the operations in blocks 202-224 one or more times. The developer may use the authoring GUI 10 to add (at block 202) graphical shapes to a first level node template 52, 92, where each shape comprises a node representing a task to perform in the task model. The authoring GUI 10 may be used to create (at block 204) links between the first level nodes in the first level template 52, 92 representing a logical ordering and flow of the tasks represented by the first level nodes. The developer may select (at block 206) one first level node (graphical shape) to open a second level node template 72, 112 for the selected first level node, e.g., task 2 in first level template 52 FIG. 2 and analyze data task 100 in template 92 (FIG. 4). The authoring GUI 10 may be used to add (at block 208) graphical shapes to the opened second level node template 72, 112, where each added shape comprises a second level node representing a step to perform. A content object may be associated (at block 210) with each second level node in the opened second level node template 72, 112. A content object may comprise a file having text or hyperlinks to launch application programs or links to further pages of information. The developer may use (at block 212) the authoring GUI 10 to create links between the second level nodes in the selected second level node template 72, 112 representing a logical ordering and flow of the tasks represented by the second level nodes.

The developer may further add (at block 216) a reusable task, such as the reusable tasks in edit pane 54 (FIG. 2) to the first level template having a predefined template of second level nodes. A reusable set of steps may be added (at block 218) to one second level node template having predefined content objects for the reusable set of steps. Upon receiving (at block 220) modification to one content object in one reusable set of nodes, which may be modified via the authoring GUI 10, the authoring system 8 may automatically (at block 222) propagate modifications to the content objects in all task models in which the reusable set of nodes was added. The developer may then use (at block 224) the authoring GUI 10 to export (at block 226) the first level template 14 and second level templates 16 to create an end-user graphical user interface 20 to perform the operations represented by the flow of tasks and steps for the tasks in the templates. For instance, the authoring system 8 may convert the templates 14, 16 of nodes and their associated content objects into a series of hypertext markup language (HTML) or Extensible Markup language (XML) pages that include links to other pages according to the logical ordering represented by the links in the first level and second level templates to enable the end-user to navigate through the pages according to the logical ordering indicated in the first and second level templates. Alternatively, the templates comprising the task model may be archived, stored or otherwise provided to an application or external component.

Described embodiments provide techniques to provide multiple levels of ordering of content objects and tasks related to the processing of those content objects. The flow represented by the templates comprising the multiple levels of ordering form a task model representing an overall task to accomplish, such as diagnose a technical problem with a device or program, perform a set of organizational operations to complete an overall business or technical task, process content objects, provide a guided tutorial through steps rendering the content objects, etc. The templates and their indicated logical ordering are used to generate an end-user user interface that enables the user to proceed through a structured series of steps to process and use content objects, which may comprise documents and programs, in the logical ordering indicated in the templates. This described authoring tool allows the developer to define a structure for documents, programs and a process that may be otherwise maintained or utilized in an unstructured format.
